Your own e-mail domain: professional communication in the net

Your own e-mail address is one of the most important contact data on the Internet. However, most e-mail users still miss the opportunity to convey a professional impression with their own mail domain. Instead, freemail providers enjoy great popularity. These provide a solid service for free, but in professional communication are not very serious. The reason for this is the brand name of the mail provider in the address, for example:

[email protected]

No matter which provider you choose, the structure of the e-mail address is always the same. In order to allow a clear assignment of sender and recipient, e-mail addresses worldwide consist of two basic components: a Local Part and a Global Part. Whereas the Local Part before the @ sign corresponds to the user name of an e-mail account, After the @ sign, the Global Part indicates the mail domain – the subarea of ​​the domain name system in which the address resides. One therefore speaks of the domain part. This consists of a host name and the top-level domain (TLD). While freemail customers can only freely choose the local part of their address below the provider domain, their own e-mail domain allows an individual address:

[email protected]

[email protected] 

What you should consider in your own mail domain

Users who want to register their own email domain choose any top-level domain and domain name availablewithin the desired namespace. It should be noted that each domain name below a TLD is assigned only once. Which endings are available depends on the provider. If a desired name is assigned under a certain TLD, users can switch to another extension. The new domain extensions (nTLD) offer good opportunities to create a “talking” domain name or to establish a regional connection:

It should be noted, however, that the rules on which domain names are formed are defined by the respective issuer of the TLD . Basically, for all top-level domains, domain names can be formed from the letters a-z, the numbers 0-9 and hyphens. Case-insensitive is not distinguished. Some TLDs such as .de also allow special characters such as umlauts in the domain name. However, use in mail domains is generally not recommended, as umlaut domains can cause problems with mail servers and email programs.Domain CheckCheck Now

What advantages does your own e-mail domain offer?

Your own e-mail domain has numerous advantages over freemail addresses, which can essentially be summarized in six points:


Professional success stands and falls with a serious appearance. This also applies to e-mail communication. While freemail addresses with provider domains generally give an unprofessional impression, entrepreneurs and the self-employed secure their own mail domain with trustworthy contact addresses – personal or task-oriented as needed :

[email protected]
[email protected] 
[email protected] 

[email protected]


At popular freemail providers, millions of email customers communicate under one and the same domain. Accordingly, it is difficult to register a succinct user name. As a rule, common combinations of first and last names are already filled, so users inevitably have to resort to number combinations:

[email protected]

Such an address not only contains typo potential, it is also hard to remember. The own e-mail domain, however, allows short, memorable contact addresses .


With its own mail domain, e-mail users secure far-reaching independence from the respective mail provider . Should a provider restructure its product range or discontinue the business, a domain owner can easily move to another web host with his own email address. In Germany, domains have a property-like status. For example, a .de domain is considered a legally protected asset. On the other hand, it is different with a user account under a provider domain. Here, the provider change is always associated with the change of the e-mail address. 


Freemail accounts are usually associated with advertising. But not only the free providers use the pool of e-mail customers to spread advertising messages. Due to the uniform scheme [email protected] , freemail addresses are also a popular target for spam . The own e-mail domain, on the other hand, relies on a payment model, does not require any provider advertising and minimizes the risk of spam. 


Cybercriminals also hope for a high hit rate when distributing malicious programs such as viruses or Trojans in a scattering process to freemail users. Free mail providers are a popular destination for hacking attacks and phishing methods. Having your own mail domain reduces the likelihood of hacker attacks. 

Typo Resistant

Correctly configured addresses with their own mail domain are much more reliable than freemail addresses. The catch-all feature makes it possible to redirect incoming messages to a domain to a main mailbox, even though the local part before the @ sign can not be mapped to a specific mailbox due to typing errors. This avoids the loss of important messages. 

How to set up your own e-mail domain

In principle, the registration of a mail domain with each provider follows the same pattern: You select a domain name of your choice under the desired top-level domain and check the availability via the search mask of the mail provider . If the domain name under the chosen TLD has already been assigned, you will be offered variants with other domain extensions or alternative domain names. Once you have decided on an available domain, you will be guided through the ordering process step by step . How this works, we show you here:

Step 1: Select provider

NICs cooperate with various Internet service providers. One and the same domain can usually be registered via various service providers. Important selection criteria for mail hosting with your own domain are the number of mailboxes provided, the storage space per mailbox and the availability of relevant transmission methods such as POP3 and IMAP. In addition, you should find out where your personal data is stored with the respective provider. Only if the computer center is located on German soil, the local data protection regulations apply. 

Step 2: Check the mail domain

If a suitable mail hoster is found, it is necessary to check the availability of the desired domain. Accredited registrars have a free domain query available:Domain CheckCheck 

  • .of
  • .email
  • .with
  • .

Desired domains that you enter into the search mask are queried by the respective provider within seconds at the respective registry. Keep in mind that a mail domain must always consist of a top-level domain and a second-level domain name.

Since the desired domain is assigned to the .de namespace, the request is addressed to DENIC as the responsible registry for the selected top-level domain. If there is already an entry for this combination of domain name and TLD, the request will be rejected and the registrar will inform you that the desired domain has been assigned:

If the desired domain is occupied, you have two options: Either you change the domain name or you check the availability of the second-level domain (here: “example-company”) in combination with other top-level domains. Sometimes the registrar already offers a selection of alternative endings (instead of .de eg .berlin or .com).

Step 3: Register your own e-mail domain

If an available domain is found, the ordering process can be initiated. For companies or online projects, it may be useful to register the desired second-level domain under different endings to increase the visibility in the network and to protect the company name from domain grabbing . 

A domain registration can now be completed online. Simply complete the order form. Your name, address and e-mail address are usually required. In addition, you must specify the appropriate bank details that should be used for the order process.

Create your own e-mail address

Depending on the mail hosting you have booked, you can create a certain number of e-mail addresses under your e-mail domain and make individual settings for forwarding, out-of-office notes, encryption options or filters. To manage your mailboxes , mail hosts typically provide a centralized control panel for the entire email account. You can reach this via your customer number or your user name and a personal password. In the control area there is usually a button “new e-mail address” . To add a new mailbox to your account for your own email domain, just define a new Local Part (the section before the @ sign) and combine it with the Global Part (domain name plus TLD):
